5.
Clean the filter head. Thinly apply oil to the packing of the
new filter cartridge and install the cartridge to the filter
head.
Replace inner seal (3) with a new one.
NOTICE
• Do not fill the new filter cartridge with fuel.
• Remove cap (B) at center and install the filter car-
tridge.
6.
When installing the cartridge, tighten it until the packing
surface contacts the sealing surface of the filter head, then
tighten it 3/4 of a turn.
If the filter cartridge is fastened too much, the packing will
be damaged and this leads to leakage of fuel. If the filter
cartridge is too loose, fuel will also leak from the packing.
Therefore, be sure to observe the tightening angle.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
7.
Turn valve (1) at the bottom of the fuel tank to OPEN posi-
tion (O).
8.
After completing the replacement of filter cartridge (2),
bleed air from the circuit.
METHOD FOR STARTING ENGINE USING FUEL FEED PUMP
1.
Fill up the fuel tank with fuel (to the level where the float is at the highest position).
2.
Loosen the knob of feed pump (4), pull it out, then pump it in and out until the movement becomes heavy.
3.
Push in and tighten the knob of feed pump (4).
4.
After replacing the filter cartridge, start the engine and run
it at low idle for 10 minutes.
If the engine does not start, repeat steps 2 and 3.
Keep away from the engine while it is being started and
running.
5.
Check the filter seal surface for fuel leakage.
If the leakage is noticed, check the filter cartridge for its
tightening condition.
If oil still leaks, remove the filter cartridge.
If foreign material is caught, replace the cartridge with a brand new one.
For details, see “METHOD FOR REPLACING FUEL MAIN FILTER CARTRIDGE”.
6.
After the engine starts, run it for approximately 5 minutes to bleed all air from the fuel circuit.
7.
After approximately 5 minutes, stop the engine. Then, start the engine as usual.
